winds blowing. in the night it will drop down to the 20's. without electricity, as you move closer to that epicenter where there has been really no electricity since the earthquake and tsunami, that's where the concern really is. you can't get food in there. the infrastructure in a lot of these areas is gone. a road just up the street from us, i took a picture of it yesterday is buckled. it's hard to even explain how this road looks. cracks and buckled as if somebody took a sheet and shook it out. that's the situation, shepard in much of this northern part. that's a concern because as that situation continues, as that area spreads of evacuation, 35, 40 miles now to the outskirts of that area, you can't get in there to get these people food and supplies and the u.s. military, of course, can't get in there as well, shepard, because of the threat of the nuclear contamination. >> shepard: adam, the japanese government has just confirmed what we have been reporting from the nuclear regulatory agency here, and that is that there has, indeed, been an explosion at unit number 2 at the nuclear facility about which there has been so much concern.
